nsrr_ttldursp_f1
Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from polysomnography
|
Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from polysomnography
Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater). |
